THREE LITTLE KNOWN SPECIES OF NORTH CAR- 
OLINA FUNGI. 
BY J. G. HALL. 
It is my purpose to take up three species of fungi that are 
little known in North Carolina, and in fact in the United 
States, and to give a brief description of them. 
The first two belong to the Hyphomycetes of Saccardo, 
but to different groups under this head. The third belongs 
to the Pyrenomycetes, and the family Sphaeriaceae. 
The first I have preferred to call by the known name of 
Martensella pectinata, although as will be seen later, there 
are sufficient differences to make it a new species. It was 
first described by Coemaus in 1863 from Belgium. 
This fungus is new to North Carolina, and in so far as I 
have been able to determine, has not been reported in print 
from the United States, although I know it to be in culture 
in one other place than West Raleigh. 
The discovery of this species was partly an accident. Last 
December I was making some plate cultures from some soil 
that came from New Bern, in the eastern part of the State, 
for Sclerotinia, a lettuce disease upon which we have con- 
ducted a series of experiments. 
In the culture I noticed growing a fungus that at first I 
took to be Botrytis, but upon microscopic examination found 
to be Martensella. 
The fruiting hyphae stood erect and unbranched, except 
for the short spore bearing stalks, although later I found that 
the fungus became branched, and some times very much so.
